Generic Viagra, like its brand-name counterpart, can cause side effects. Common ones include headache, facial flushing, nasal congestion, and upset stomach. These are usually mild and temporary.
More serious, though less common, side effects include prolonged erection (priapism), vision changes (blurred vision, blue tinge), and hearing loss. Seek immediate medical attention if you experience any of these.
Certain medications interact negatively with Viagra. Nitrates, commonly used to treat heart conditions, are a serious concern. Combining them can cause a dangerous drop in blood pressure. Alpha-blockers, often prescribed for high blood pressure or prostate problems, can also increase the risk of low blood pressure when taken with Viagra.
Other medications that may interact include antifungal medications like ketoconazole and itraconazole, certain antibiotics, and HIV protease inhibitors. Always inform your doctor about all medications, supplements, and herbal remedies you take before starting Viagra.
Alcohol consumption can worsen Viagra’s side effects. Limit or avoid alcohol while using this medication. Grapefruit juice can also interfere with Viagra’s metabolism; avoid excessive consumption.
